4G Electronic Monitoring Bracelet Physical Tamper Electronic Monitoring Ankle Bracelet

Product name: Electronic monitoring bracelet Product model: YX-578B 1. Electronic monitoring bracelet function: (1) Power-on management: Only through the background system can the electronic bracelet be shut down (Background system: location management/remote control/shutdown) to prevent the wearer from shutting down illegally. (2) Display function: The device interface can display signal, name, power, time, date, ID, unread messages and alarm information. (3) 4 Relocation: Where there is GPS/Beidou signal outdoors, GPS/Beidou positioning is used, and where there is no GPS/Beidou signal indoors, it will automatically switch to WIFI or LBS base station positioning. (4) Real-time positioning: The system can position and monitor target personnel 24 hours a day. (5) Timing positioning: According to management needs, indirect positioning monitoring can also be implemented, that is, monitoring information is sent to the background at a certain time interval. (6) Track monitoring: Through the background system, the activity track of the wearer of the electronic bracelet can be queried within a certain period of time. (7) Electronic fence: You can set the range of activities for the target person on the electronic map through the background system in advance. When the electronic bracelet wearer exceeds the electronic fence area, the system will immediately send an alarm message to the system management background. (8) Disengagement alarm: The bracelet has its own locking device, and the electronic bracelet can only be removed by cutting the strap or breaking the seal. When the electronic bracelet is illegally opened and left the skin, the built-in sensor of the bracelet will immediately send an alarm message to the background system, and there will also be warning messages on the electronic bracelet for the wearer to view. (9) Power warning: When the battery level of the electronic bracelet is less than the working standard/about 10%, the electronic bracelet will send out a vibration reminder to remind the user to charge in time, and the warning information will also be sent to the computer background management system immediately. (10) Information interaction: The system can send various notification messages to the electronic bracelet through the background to maintain timely communication with target personnel.  2. Positioning mode of Electronic monitoring bracelet: (1) GPS positioning: The GPS positioning accuracy is composed of 28 satellites (4 of which are spare) distributed on 6 orbital planes separated by 60 degrees, and the distance from the ground is about 20,000 kilometers. It has achieved a single-machine navigation accuracy of about 10 meters, and with integrated positioning, the accuracy can reach centimeter-level and millimeter-level. However, the accuracy of the civil field opening is about 10 meters. (2) Beidou positioning; Beidou satellite navigation system is composed of three parts: space segment, ground segment and user segment. It can provide high-precision, high-reliability positioning, navigation, and timing services for all types of users around the world around the world. It also has short message communication capabilities, and already possesses regional navigation, positioning and timing capabilities. The positioning accuracy is 10 meters, the speed measurement accuracy is 0.2 meters per second, and the timing accuracy is 10 nanoseconds. (3) LBS base station location; base station location service is also called mobile location service, which is generally applied to mobile phone users. It obtains the location information of mobile terminal users through the network of telecommunications mobile operators, and provides users with the support of the electronic map platform. A value-added service of the corresponding service, the accuracy of base station positioning cannot be compared with satellite positioning, but it has conditions that cannot be met by satellite positioning and can be used for indoor positioning. Generally, base station positioning is more suitable for indoors. (4) WiFi positioning; WiFi real-time positioning uses the existing wireless network, cooperates with WIFI tags and related mobile terminal devices such as WIFI mobile phones, PDAs, laptops, etc., and then combines the corresponding positioning algorithms to determine the location of relevant personnel and objects A new technology. Ruiyi Industrial's community correction bracelet has a built-in WIFI positioning module, which can realize WIFI positioning for the correction bracelet. The advantage of wifi positioning is fast, but the disadvantage is that the position information depends on the analysis of the third-party platform and drift will occur.
